Introduction

DC DC Converters are device used to convert a direct current (DC) power supply into another form of DC power supply. The type of DC DC Converter used depends on the requirements of the application. The REC15-485.1S/H3 is one specific type of DC DC Converter that is designed specifically for DC motor applications. This article will discuss the application field and working principle of the REC15-485.1S/H3 DC DC Converter.

Application Field

The REC15-485.1S/H3 DC DC Converter is designed to convert a DC supply to a DC supply of a lower voltage, suitable for driving high torque DC motors in applications with limited space. This type of DC DC Converter is particularly well suited for applications requiring high current, such as in robotics, motion control, instrumentation, and medical equipment systems. The REC15-485.1S/H3 is capable of providing a high switching frequency and has a low output voltage ripple. Additionally, the converter is equipped with fault protection, current limit, overvoltage protection, and temperature protection.

Working Principle

The REC15-485.1S/H3 is an integrated DC DC Converter. The converter employs a switching regulator topology with synchronous rectification to achieve high efficiency. The converter consists of two stages, a switch-mode power stage (SMP) and a linear post-regulation stage (LPR).The SMP stage exhibits a high frequency switching operation that enables efficient and fast conversion of the DC voltage. The SMP controller controls the current flow in both directions through the power MOSFETs. This means that the current passing through the SMP port can be controlled to a precision level. The switching frequency of the SMP stage is determined by the SMP controller and is adjustable from a few kHz to hundreds of kHz. The LPR stage is used to provide precise voltage regulation and ripple rejection. The LPR controller monitors the output voltage from the SMP stage and adjusts the output voltage accordingly. This allows the LPR stage to maintain a stable and reliable output voltage, with a low ripple.

Conclusion

The REC15-485.1S/H3 is a DC DC Converter designed for DC motor applications. It is suitable for applications where space is limited and high current is required. It is equipped with features such as fault protection, current limit, overvoltage protection, and temperature protection to ensure that the motor operates safely and efficiently. The converter employs a switching regulator topology with synchronous rectification, which ensures high efficiency. The switching and linear post-regulation stages allow precise voltage regulation and ripple rejection.
